What is the exact error, and an which line is it being reported on.

Could you also post your real code. The code you posted above will only call MainForm() if there are no command line parameters, yet you are passing in args[0]. You should have gotten an IndexOutOfRangeException if that were your real code.

program.cs

 static void Main(string[] args)
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            if (args.Length == 0)
            {
                Application.Run(new MainForm());
            }
            else 
            {
                Application.Run(new MainForm2(args));
            }

Thanks for posting the code.

In post #14, you reported the double clicking on the file just gave you an empty datagrid. Since you didn't report that a message box saying "Error: File don't exist." that would indicate two possibilities:
1. The code went to line 42 of MainForm2.cs; or
2. The code went to line 7 of Program.cs.

The only true way to find out is to attach a debugger. See my post #15 to see how to do that.

AdamSpeight2008 and I have been encouraging you to set the command line arguments in the project settings to help with debugging, and I've also given you another option to debug by attaching to a running process. You seem to be ignoring these. Please just tell us if you are avoiding these because you have no interest in using a debugger and would rather just be running the code in a trial and error approach.

If you are thinking of software development as a career, in the modern world you have to learn how to use a debugger unless the only thing you want to develop is plain HTML with no Javascript. Yes, the approach of not using a debugger and just observing the behavior and putting in some strategic printf()'s or message boxes or commenting out portions of code may work, but your development velocity will be dramatically slower as compared to being at actually observe your program in action.

You still didn't answer our question about where you said you were debugging in the IDE and if you were setting the command line arguments.

Anyway, since you've chosen to take a different tack on debugging your problem, we'll have to debug things the hard way:

In your Main() method, even before the Application.EnableVisualStyles() call, add:

MessageBox.Show("Attach to me");

Rebuild and re-install your application. After you deploy you program, copy the .PDB file into the same directory that has your .exe file.

Next, double click on your .pld file.


The message box should show up.

Start Visual Studio, and choose: Debug.Attach to Process... Is the process list, you should see your .EXE as one of the choices. Click "Attach". Visual Studio may ask you to point to where your source files are.

Next, set a breakpoint on your line right before where you check the args.Length.

Let your program run, and press OK on the message box. Your breakpoint should be hit. You can then inspect the args array variable to see what command line is being passed to you. You can further trace in, and or set breakpoints in the code where you are trying to open the file.

This one was the output after all:
args {string[0]} string[]
args.Length 0

FileCompressionandDecompression.exe!FileCompressionandDecompression.Program.Main(string[] args = {string[0]}) Line 23 C#

So, the string that have been pass into my MainForm2.cs is 0.

I can figure out now my problem. My problem is in the MainForm2.cs. In reading the file into my datagridview.

[Skydiver]

Huh? If args.Length == 0, then MainForm2() shouldn't be called based on your code in post #16.

What is the value of args[0]?
